f33111a9c2 gnrc_sixlowpan_iphc: remove duplicate gnrc_netif_hdr_get_netif() 
The interface is already fetched in the beginning of the function and
doesn't change during its run, so getting the interface again at this
point is just redundant.

806f33fce4 gnrc_sixlowpan_iphc_nhc: determine UDP hdr length from RB 
When decoding IPHC in a fragmented datagram, relying on the size of the
allocated space for the decoded packet is wrong when fragments are
forwarded and decoded on an intermediate node (for which the reassembly
buffer's space is used): Using the full datagram size for allocation in
this case would be wasteful, so the allocated space is only marginally
larger than the fragment's compressed form.
This in turn results in the wrong UDP payload size being chosen and
even worse being forwarded to the subsequent nodes.

This change uses the (virtual) reassembly buffer's `datagram_size`
instead of relying on the allocated space for the encoded
datagram/fragment.

f8d75d7add gnrc_sixlowpan_frag_rb: behavioral change to add() 
Rather than dispatching the packet automatically once it is complete,
`gnrc_sixlowpan_frag_rb_add()` now only returns success, and leaves it
to the caller to dispatch the packet.

3582dedd4e gnrc_sixlowpan_iphc: check ptr != NULL in compressible check 
Not only does this leave open a risk to crash the node for the check
in `_compressible()` but also is the `tmp` check below getting confused
when `ptr` is `NULL`, since `gnrc_pktbuf_start_write()` returns `NULL`
in that case.

43c2c728c9 gnrc_sixlowpan_iphc: fix _compressible() 
When either `gnrc_sixlowpan_iphc_nhc` or `gnrc_udp` is not compiled
in `_compressible()` never returns `true`. This causes the
`dispatch` snip in `gnrc_sixlowpan_iphc_send()` to be of length 0,
meaning `dispatch->data` is `NULL`, causing possible crashes when
trying to send IPv6 packets over 6LoWPAN without NHC or UDP.

69d9ecc0d9 gnrc_sixlowpan_iphc: refactor reception for #8511 
This refactors reception/decoding part of `gnrc_sixlowpan_iphc` to the
more layered approach modeled in #8511. Since the reception part is
already complicated enough I decided to divide send and receive up into
separate changes.

faa47a0e03 gnrc_sixlowpan_iphc: Fixed encoding when COMP=0 
Summary:

Even ehen COMP is cleared, the algorithm always elides part of the address when a matching
context is found.

This behviour occurs because in the line

  if ((src_ctx != NULL) || ipv6_addr_is_link_local(&(ipv6_hdr->src)))

the COMP bit is not tested.

This patch fixes the problem by setting [src|dst]_ctx to NULL if the
context must not be used.
